OpenStatus is an open-source uptime and synthetic monitoring platform. Its main purpose is to monitor APIs and websites globally and showcase reliability with a public status page. Key features include global uptime and synthetic monitoring for APIs and websites. It provides a public status page to showcase service reliability. The platform is open-source, allowing for community contributions and transparency. It offers a free tier to get started. For MCP servers specifically, the tool performs a true protocol-level check, acting exactly like a real AI client. It goes beyond basic HTTP pings to validate the actual JSON-RPC handshake required for AI agents to function. The MCP Health Checker provides deep visibility by inspecting exact JSON-RPC payloads and negotiated versions. It offers smart authentication parsing, analyzing RFC 9728 headers on 401 responses to surface exact token requirements. This helps developers debug connectivity issues that standard uptime monitors would miss. The product benefits developers and teams building and maintaining MCP servers by ensuring their endpoints are truly functional for AI clients like Claude Desktop or Cursor. It solves the common problem where a server returns a 200 OK HTTP status but fails during the JSON-RPC handshake, which breaks AI agents. Target users are developers working with the Model Context Protocol (MCP) and AI agents. It is particularly useful for those building MCP servers who need to ensure protocol compliance and real client connectivity. The tool is open-source and integrates with the broader OpenStatus synthetic monitoring platform.
